Technical description

A reflected cross-site scripting vulnerability exists in x-ui 0.3.2. The management interface reflects the raw request URI into a client-side template binding expression used for sidebar menu highlighting. Server-side HTML entity escaping is ineffective in this context: the browser decodes the entities before the client-side framework evaluates the content as a JavaScript expression. A logged-in panel user who visits a crafted URL allows arbitrary script execution in the same-origin context of the management page, enabling data theft and unauthorized actions through the victim's session.

———Cross-site scripting in the embedded co-browsing feature in Unblu inc. Unblu Spark 7.0 through 7.57.7 and 8.0 through 8.39.2, on on-premises and cloud deployments, allows an unauthenticated remote attacker in the visitor role to execute arbitrary JavaScript in the browser of an agent taking part in the attacker's co-browsing session, via content of the co-browsed page that the agent's browser renders as HTML. The JavaScript runs in the context and under the identity of the agent's session in the Agent Desk or the Single Conversation Desk. Exploitation requires an agent to join an embedded co-browsing session with the attacker. Mobile co-apping isn't affected.4h CVE-2026-1135836.1 MED

Attackers can send a specially crafted email so that when the victim opens it, the externalResources.js code builds the blocked-image notice using innerHTML with decoded email-derived values, triggering script execution in the victim's authenticated session to read mailboxes, send email, or change settings.4h CVE-2026-1133834.3 MED
